You forgot the 3rd answer :
There can be a 1080 Switch with more battery and a noticable upgrade on GPU for higher resolution and higher framerate, but nothing which will allow to port games from the next era like ReviewTechUsa believes.
Games native to next gen will take time though. It usually takes at least 3 years to be at that point. I'd say it'll be possible for the Switch to get games during the first 2 years of the PS5/XboxTwo.
